摘要： An input analog signal is converted into a corresponding digital signal. A predetermined time segment of the digital signal is selected. A memory stores the selected time segment of the digital signal. A line counter counts horizontal scanning lines of an output video signal. The selected time segment of the digital signal is read out from the memory in synchronism with a horizontal sync signal in a direction of a time axis. An output signal from the line counter and the readout time segment of the digital signal are compared, and a video signal is generated which represents a waveform of a time segment of the input analog signal which corresponds to the selected time segment of the digital signal in synchronism with a vertical sync signal. The video signal is fed to the display section of the television receiver, and the waveform is indicated by the display section of the television receiver.

摘要： A color picture display apparatus is provided having a driving circuit for a display device so that a low light adjustment is not influenced by a high light adjustment during white balance adjustment. Horizontal blanking period is blanked by a transistor and a clamping potential of a low light level for white balance adjustment is added to the above blanked signal. The signal, to which a clamping potential was added, is gain-adjusted and clamped by a capacitor and a transistor. Next, the clamped portion is blanked at a transistor and the blanked signal is supplied to a CRT through a driving stage. Low light adjustment is done by adjusting clamping potential with a potentiometer and high light adjustment is done by adjusting gain with another potentiometer.
